Is your substrate still moist? does it clump when you squish it together? I am not familiar with JCP eggs but reptile eggs in general can look pretty funky and still hatch fine. If they were dead they would mold with a week or two. All eggs will wrinkle as the closer to hatching (2-3 weeks before). Check substrate(make sure it's not dried out) and make sure the tubs are sealed up so they aren't getting any breeze or strong airflow on them and caising them to dry up.
